, useful Fuel-Feedin Apparatus, of which the I passage-way extending inatangential direc following is a speci cation. 4

My invention relates to fuel-feeding apparatus, and more articularly tomeans for delivering the pul verized material from thepulverizing-cylinder to the furnace; and it consists, broadly, inproviding the periphery of the cylinder, near its discharge end, with ation from the periphery of the cylinder and curving into the plane ofthe longitudinal axis of the cylinder, extending thence away to thepoint where the pulverized material is to be used.

A practical embodiment of my invention is represented in theaccompanying drawings, 1n which Figure 1 is a side view of a portion ofa pulverizin -cylinder, showin it in side elevation with -t edischarge-con uit leading therefrom. Fig. 2 is a similar view in to planre-' presenting two discharge-conduits iametrically located with respectto each other, and Fig. 3 is a transverse section in the plane of theline A A of Fig. 2.

The pulverizing-cylinder, in which the material to be fed to the furnaceis reduced to a finely-pulverized or floured condition, is denoted by 1.At'its discharge end it is provided with one or more discharge-conduits,in the present instance two, which extend from its periphery in atangential direction, as denoted at 2 and 3, in the present instance atoints diametrically opposite each other an which after following thecurve of the cylinder a short distance (denoted at 4 and 5) graduallycurve into the plane of the longitudinal axis of the cylinder, as shownat 6,

- Fig. 1, and then gradually converge, as shown at 7 and 8, Fig. 2,until theyunite and form a single discharge-passage 9, which may becontinued directly either in a right line or in suitable curved lines,as the .case may be, to the point where the fuel is to be burned in thefurnace. The size of the discharge-conduits leading from the cylinderwill naturally depend upon the number of such conduits employed,which'may be one or more, but preferably two, as shown.

. It has been found by experience that the pulverized fuel will benaturally discharged 1n atangential direction under centrifugal force atthe periphery of the cylinder with greater conformity and freedom thanat any other point, and at the same'time it becomes important,particularly in connection with locomotives, that the flow of thepulverized material should be in a direction correspondin to thelongitudinal axis of the pulverizing cy inder at a point as near thedischarge end of the cylinder as may be feasible; To this end I haveprovided the curved conduits which utilize the centrifu al action tostart the flow and then prompt y convert it by a gradual turn into aflow directly away from the cylinder in the longitudinal direction ofthe same.

. What I claim is 1., The combination with the cylinder, of adischarge-conduit extending tangentially from the periphery of thecylinder and gradually curved into a position extending in a directioncorresponding to the longitudinal axis of the cylinder.

2. The combination with the cylinder, of a plurality ofdischarge-conduits extending tangentially from the peri hery of thecylinder and gradually .curved and merged into one conduit extending ina direction corres onding to the longitudinal axis of the cyliner. a
